A bulging disc is one of the earliest signs of normal spinal wear. As a disc loses some of its water and height with age, its outer wall spreads outward past its usual edge — a bit like a tire that flattens slightly under weight. The wall stays intact, and the soft center stays contained, which is what separates a bulge from a full herniation.
Bulging discs are extremely common, and many show up on imaging in people who feel nothing at all. A bulge only matters when it broadens far enough, or in the wrong direction, to crowd a nearby nerve root. When that happens the pain typically follows the nerve into an arm or a leg rather than staying local.
Your spine is made up of stacked vertebral bones with a disc between each. The spinal discs provide support, allow for movement between bones, and help prevent the bones from rubbing against one another. They are also shock absorbers.
Literature will refer to “bulging,” “herniated,” “ruptured,” and “protruding” discs interchangeably. However, Dr. Melamed distinguishes between these terms: a bulging disc involves a protrusion without a break in the annulus (the outer fibrous ring), while a herniated disc involves a protrusion with a break that allows contents to leak out. In practical terms, both descriptions refer to the same concern: whether the disc is close enough to irritate or compress spinal nerves and other structures.
✓Radiating discomfort into an arm or leg if a nerve is crowded
✓Numbness or tingling along the affected nerve's path
✓Pain that worsens with prolonged sitting or bending
✓Mild weakness in a hand or foot in more advanced cases
Symptoms will vary according to the location of the bulging disc and whether a nerve is being irritated or pinched. Other symptoms can include:
Loss of range of motion or ability to move easily
Possible back spasms
Sciatica-like symptoms if the bulge is in the lower back, since the sciatic nerve can be affected by lower back issues
One set of symptoms should be treated with special urgency: loss of bowel or bladder control suggests a rare but serious emergency involving nerve compression, often referred to as cauda equina syndrome. Immediate medical attention is needed under those circumstances.
Common Causes and Risk Factors
Age-related drying and flattening of the disc
Repetitive bending, sitting, or loading of the spine
Poor posture and weak core support over time
Prior minor injury or strain to the back or neck
Smoking and genetics that accelerate disc wear
Bulging discs are often associated with age-related changes in the disc itself. Dr. Melamed says that discs tend to lose flexibility as people age and that spinal discs often lose water content and become more brittle over time. He states that the condition is described as developing gradually over time, with one possible precursor being a tear or fissure in the annulus that develops slowly and then contributes to the bulge.
Injury can also cause a bulging disc. An accident (such as a car accident or fall) can contribute to the development of issues with spinal discs, and injury may also worsen symptoms.
Other risk factors include:
Degenerative changes associated with age, which may occur more frequently after age 40
Being overweight or obese
High-impact sports
How Beverly Hills Spine Specialists Diagnose Bulging Discs
Because bulging discs are so common on imaging, Dr. Melamed is careful to connect the picture to your actual symptoms rather than treating the scan alone. He maps where any pain, numbness, or weakness travels and uses an MRI to confirm whether a bulge is genuinely touching a nerve or is simply an incidental finding. That distinction keeps treatment appropriately conservative.
A diagnosis can help make sure there is a match between reported symptoms and what’s occurring in the spine, while also confirming through proper imaging that this is indeed causing problems.
Imaging is also routine and vital. X-ray may be used to assess overall spine state; MRI is often used for detecting bulging discs; and CT/myelograms may also be requested if extra information needs to be gathered.
Bulging Disc Treatment Options
A bulging disc almost never needs surgery. Because the disc wall is still intact, the focus is on calming any irritated nerve and supporting the spine — targeted physical therapy, posture and core work, anti-inflammatory measures, and sometimes an image-guided injection if a nerve root is inflamed. Many bulges quiet down and stay quiet with this approach.
In the uncommon case where a bulge progresses toward a herniation and produces persistent radiating pain or weakness, Dr. Melamed favors the least-invasive route. If a procedure is ever warranted, biportal endoscopic surgery (BESS) allows him to decompress the crowded nerve through incisions under a centimeter without cutting muscle, preserving your own disc and motion. Surgery here is genuinely a last resort, not a first move.
Dr. Melamed’s approach is conservative treatment followed by precise surgical options when necessary. Being conservative is the best approach because multiple reviews suggest that up to about 90% of herniated or bulging disc cases improve over about 6 months with non‑surgical care, such as physical therapy, activity modification, targeted exercise, and medications, which explains why conservative care is usually the first‑line recommendation in Beverly Hills clinics.
Treatment is typically guided by the severity of any symptoms, the location of the bulge, and whether there is nerve compression caused by the bulging disc. Dr. Melamed uses a holistic approach to bulging discs, which may include elements from integrative medicine, chiropractic medicine, and acupuncture.
Dr. Melamed may recommend simple exercises and behavior changes (including smoking cessation), as well as non-opiate medications to address some of the pain and discomfort.
Another reference mentions non-surgical options for treating cervical bulging discs, such as:
Physical or chiropractic therapy with stretching and strengthening exercises
Nonsteroidal anti-inflammatory drugs (NSAIDs) or other over-the-counter medications for pain relief and inflammation
Massage therapy to help relax muscles
Injectable anti-inflammatory medications
Rest
Some procedures may be considered if conservative treatments are not successful over time. Dr. Melamed mentions three uses:
A microlaminotomy is a minimally invasive surgery that opens up the spinal canal with a very small incision, providing more space for displaced tissue causing the bulge.
A microdiscectomy is the removal of some or all of the structure that’s causing issues.
A spinal fusion may be chosen to improve stability and reduce pain by joining the vertebrae.
Surgery becomes relevant when symptoms are severe or serious enough to require addressing the underlying cause.
Ideally, if there’s an option for non-invasive treatment, that’s what is recommended. Many cases improve without intervention; one reference states that most cases of herniated discs will heal and resolve with non-invasive treatment.
If an untreated bulging disc becomes a herniated disc and surgery is required, minimally invasive techniques are emphasized.

Conservative Treatment Tips for a Bulging Disc · Dr. Hooman Melamed on YouTube
Usually not. Bulging discs are a common part of normal aging and often cause no symptoms at all. One only becomes a concern if it broadens enough to press on a nerve, producing pain, numbness, or weakness that travels into an arm or leg. Even then, treatment is almost always non-surgical.
Can a bulging disc turn into a herniated disc?
It can. A bulge is an earlier stage of the same process, and continued wear or a strain can cause the outer wall to tear so the soft center pushes through. Keeping your core strong, protecting your posture, and avoiding heavy repetitive loading all help reduce that risk.
Do I need surgery for a bulging disc?
Almost never. Because the disc wall is still intact, physical therapy, posture work, and anti-inflammatory measures resolve most cases. Dr. Melamed reserves any procedure for the rare bulge that progresses and causes persistent nerve pain or weakness, and even then he uses a muscle-sparing endoscopic approach.
